COMPOSITION TUB, TANK, 840.

SPEGIFIGATION forming part of Letters Patent No. 469,416, dated February 23, 1892.

Application iiled June 20, 1390. Serial No. 356,087. (No model.)

To all whom it may concern,.-

Be it known that I, WILLIAM E. CLow, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Composition Tubs, Tanks, &c., which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a perspective view of a section of a metal strip to be applied to the edges of composition tubs, &c.; Fig. 2, an elevation of the same set upon end, and Fig. 3

'a perspective View of a section of the tub itself with the strip applied.

My invention relates to the constructionof a metal strip designed for protecting the upper edges of tubs and other like vessels made from composition which is molded in plastic condition and then hardens, and also to the mode of applying said strip to the vessel and fastening it thereto.

In the drawings, A represents the metal strip after it is formed ready for application to the edge of the tub for the purpose of covering and protecting the same. This strip is of any thin sheet metal suitable for the purpose, and it 'is bent as seen in Figs. l and 2, the central or covering portion a thereof being preferably slightly curved, so as to present a con vex surface, while the sides a' are not onl y bent downward but also inward toward each other, so that they stand in a plane considerably inclined to the vertical plane of the outer edges of the strip and turned inward from the latter. In applying this strip to the tub it Will be understood that it must be accomplished while the material of the latter is in a plastic condition.

The manufacture of tubs and other vessels from composition is well known and requires no description here. The vessels are produced by forming up the plastic composition in a suitable mold.

In carrying out my invention the strip A, formed as described and shown, is placed in a suitable position in the mold for the tub or other vessel, and the plastic material being then introduced into the molds will be pressed into and fill the space bounded by the bent strip, and will of course pass up also on the outside of the inwardly-bent flanges a', so

of the inwardly-bent portions of the strip the composition will extend upward to the extreme upper edge of the strip, or the point where the bend begins, thus forming-a triangular-shaped portion b' of the composition around the outside of the inwardly-inclined strip sides a'. Fig. 3 of the drawings, and it is obvious that by reason of the inward bend of the strip sides and the complete embedding of these bent sides in the material of the vessel the strip is securely fastened to the edge of the vessel without any special device for this purpose. It is permanently secured to the vessel, so that it cannot be removed without destroying the latter, and it makes a complete and ornamental finish and protection for the tub. The convex form of the strip is not naterial. The body a may be horizontal, if preferred, but the convex form makes the better fiush.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a composition tub or other like vessel, the side B of the vessel, in combination with a metal protecting-strip A for the upper edge thereof provided with side flanges ct', inclined inward toward each other, the inclination beginning at each edge or cornerv of the strip and the said fianges standing in planes inclined inward from the respective faces of the tub side, Whereby they are embedded entirely within the composition material, which extends over and covers and supports the outside as well as Lhe inside of each flange the entire width thereof, substantially as described.
